+        Fix reference.md generation for APIs with multiple root-level endpoints.
+        Previously, only the last root endpoint appeared in the reference documentation because `addRootSection()` was called inside the endpoint loop, replacing the root section each time.
+        The fix moves section creation before the endpoint loop, ensuring all root endpoints are included and removing the empty `##` section header that was being generated.
